Stopped at Doc's a few weeks ago for a strawberry smoothie. I may not be much help since I rarely drink smoothies and therefore don't have a good basis for comparison, but it was tasty and the guy at the counter was very nice. The menu is somewhat limited, but they are willing and eager to mix stuff up pretty much any way you like. It is pretty bare-bones, hardly any decor at all, but definitely had a mom-and-pop vibe. You'd certainly be helping out a local business if you went there.
As far as "dodging starfruit" goes, that's a good idea--that is one pointy little fruit!
